Solution enables a battery with both high efficiency and current density.
A research team led by North Carolina State University has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared (IR) range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.
Florida State University’s Center for Advanced Power Systems has unveiled a new 24,000-volt direct current power test system, the most powerful of its kind available at a university research center throughout the world.
Berkeley Lab and UC Berkeley team engineers the shape and properties of nanoscale strips of graphene.
Finding gives scientists a new group of materials to explore to unlock secrets of some materials' ability to carry current with no energy loss.
Polarizing filter designed by University of Utah engineers transmits more light.
An electronic “tongue” could one day sample food and drinks as a quality check before they hit store shelves. Or it could someday monitor water for pollutants or test blood for signs of disease. With an eye toward these applications, scientists are reporting the development of a new, inexpensive and highly sensitive version of such a device in the American Chemical Society journal ACS Applied Materials & Interfaces.
University of Illinois at Chicago researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times.
With almost all of the U.S. population armed with cellphones – and close to 80 percent carrying a smartphone – mobile phones have become second-nature for most people.
